HOT-AIR REGISTER.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed April 9, 1912. Serial No. 689,557.

and I do declare the following to be a full,

clear, and exact description of the invention,

such as Will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

My invention relates to hot air registers and has for its principalobject to provide a device of that class whereby cold air from the lowerportion of a room may be drawn into the register and passed therethroughin contact with the register box, so that it becomes heated and isafterward delivered from an upper portion of the register to againcirculate throughout the room from which it was originallytaken,'thereby promoting circulation of air and facilitating the heatingof the room. In accomplishing this object, I have provided the improveddetails of structure, hereinafter described and illustrated in theaccompanying drawings, wherein- Figure I is a perspective view of aregister constructed according to my invention, showing its applicationto the wall of a room and its relation to the ordinary baseboard. Fig.II is a vertical section on the line IIII, of Fig. I showing thearrangement of the register box and register and the relation of suchparts to the walls. Fig. III is a horizontal section on the line IIIIIIFig. II. Fig. IV is a horizontal section on the line IV-IV Fig. II. Fig.V is a detail perspective of a register box adapted for use with myimproved register. Fig.- VI is a detail perspective of the registerlooking from the rear.- Fig. VII is an enlarged detail view of theadjusting device. Fig. VIII is a perspective view of modified form ofregistershowing an arrangement of intake and exhaust openings. Fig. IXis a perspective view of a further modification.

Referring more in detail to the parts: 1 designates interior wallsQf abuilding between which an ordinary furnace pipe 2 is located, the upperend of said pipe being provided with a register box 3 which projectsthrough one of the walls to the interior of a room, the lower edge 4 ofsaid box bemg a short distance above-the floor 5. In the bottom of thebox, near the front edge thereof, and in the upper ends of the boxsldes, are apertures 6, of any suitable size, shape or number, throughwhich air may pass into the box. Fitting over the box 3 is a register 7,which, in the preferred form,.extends upwardly from the floor 5 and hasedge and top flanges 8 whereby its face is spaced outwardly from thewall to outer edge of the box engaging the rear face of the registerbody so that channels or passages 10 are formed Within the registeraround the box. The register may be formed of either cast or sheet metaland has openings 11 in its face through which hot air from theregisterbox may be delivered into the room. Pivotally hinged at itsupper end to the rear face of the register, within the upper portion ofthe box 3, is a damper plate 12, which extends downwardly and rearwardlyinto the furnace pipe 2 and is adapted to lie against the rear edge ofthe box, as illustrated in Fig. II, the plate extending entirely acrossthe box, or pipe, so that when the damper is in its forward or closedposition no air from'the furnace pipe can pass through the box.

For adjusting the damper plate I provide a device comprising ahand-wheel 13' (Fig. VII) having an interiorly threaded hub 14 forreceiving the shank 15 of an eyebolt 16. Said shank is adapted forprojection through-an opening 17 in the register, preferably below thedischarge apertures 8, and has a collar 18 fixed thereto and adapt; edfor free rotary movement within its opening, the fit of the collar beingsufficiently close, however, to prevent lost motion or sagging of thehand-wheel or eye-bolt. On the shank at each side of the collar is awasher 19 for retaining the parts in place and covering the aperturedportion of the register.

20 designates a screw member of flat metal having an aperture 21through-Which the hook-bolt is projected, and having a free inner end 22protected through a slot 23 in the damper plate 12, so that when thehandwheel is manipulated the damper plate may be moved inwardly oroutwardly, according to the direction of the movement of the wheel. Inthe lower portion of the register are apertures 24 through which coldair from the lower portion of the room may be drawn by the risingcurrent of hot air, which is delivered through the furnace. pipe andregister box. I also preferably provide apertures 25 in the upperportion ofthe register, through which the excess volume of cold air maybe re-delivered into the room after being tempered by contact with thefurnace pipe and box.

While I have shown the register as rising flush from the floor, and withall of the air openings in the front face of the register, it isapparent that when a-regist-er is set above the floor the intakeopenings may be placed in the bottom flange, as shown in .Fig. VIII, orthe corners or flanges of the register may be fluted, as shown in Fig.IX, without departing from the spirit of my invention.

Presuming the parts to be assembled, as shown and described, withhot-air rising through the furnace pipe and being delivered through theregister, it is apparent that the rising current of heated air will tendto draw air from the channels, or passages, surrounding the register boxin through the box apertures 6, so that a continuous circulation isprovided, the cold air being drawn in through the bottom registeropenings and rising around the furnace pipe and register box to becomeheated during its passing, either entering the register box throughapertures 6 and again being delivered through the register, or risingthrough the top of the box and being delivered through the upperapertures in the face in the body of the register. It is apparent thatby inanipulating the hand-wheel 13 the area of the discharge opening maybe regulated to determine the volume of heated'air to be delivered tothe room. It is also apparent that by placing the hand-wheel-below thehot-air openings the wheel will not become heated as it is out of thepath of the hot-air.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent is The combination with a furnace'pipe for supplying heated air and having a register box provided withan open end, of a register having an apertured front portion disposedacross the open end of said box and having end flanges spaced therefromto form air channels thereabout, a damper plate having a vertical slotdisposed therein adjacent itsvlower edge, and being adapted forpositioning in the open end of said box and projecting into the furnacepipe, a screw pivotally mounted on said register and dlsposed in saidplate slot, whereby the said plate is actuated by the revolution of thescrew to regulate the volume of air from the said pipe, said registerhaving a plurality of openings disposed in its uppenand lower portionsand communicating with the air channels, to provide a continuouscirculation of air around the box, he lower openings being adapted foradmitting cold air into the channels and the upper openings fordischarging air in a heated state.

In testimony whereof I aflix my signature in presence of two witnesses.
